Well, my engine light came on about a week ago and when I got the code pulled. It came up as the speed sensor. So I replaced it and yesterday my light came on again with the same problem showing as the speed sensor. Is there anything else I can check to fix this problem? The wiring and harness looks fine. If someone could please help me I would greatly appeciate it. I need to pass emissions. By the way it is a 98' 5spd. 4x2 reg. cab 4cyl.
